PHP mail not working for some reason

Question

I am new to PHP and I'm using the mail function to send emails which is not working. I get a success message, but still it does not work

same code

<?php
    $email_to = "[email protected]";
    $email_subject = "Test mail";
    $email_body = "Hello! This is a simple email message.";


    if(mail($email_to, $email_subject, $email_body)){
        echo "The email($email_subject) was successfully sent.";
    } else {
        echo "The email($email_subject) was NOT sent.";
    }
?>

Am I missing anything, do I need to include any files for this function.. I am from asp.net & this is the basic script which found on website.

I tried other scripts related to mail they didn't work either..

I AM RUNNING THIS SCRIPT ON THE WEBSITE NOT on the localhost

If you are using Ubuntu and it seem sendmail is not in /usr/sbin/sendmail, install sendmail using the terminal with this command:

sudo apt-get install sendmail

and then run reload the PHP page where mail() is written. Also check your spam folder.
